I was downwind from Frank once at an away game & can verify he doesn't use deodrant. That'd be a long trip if you were on the same coach as him.
Frank is nearly always on Coach 1. Leave your booking till the week before and you should be safe. I was on Coach 1 with Frank at Spurs away last season. He decided to go for a number two on the coach khazi and ended up pebble dashing the porcelain and stinking the place out.
